It's ok if it needs the FS unmounted to operate. Also mounted is OK. It does not need repair capability It needs very good checking capability: it has to return Good / Bad status with the "Bad" meaning that there is at least ONE inconsistency. Good means that it is really really 100% consistent. Does something like this exists? We need to detect as much ahead of time as possible if the btrfs filesystem has become even just a little bit inconsistent Thank you
